What's the basic point of "The Diary of Anne Frank"?
I would argue that it is a "story" perse. Anne did not intend to write a story so much as she intended to entertain herself, gather her thoughts, and "grow up" during the time that she and her family as well as a few friends were hiding from the Nazis during World War II. The time had to be spent in quiet pasttimes. Writing was Anne's choice.
The diary exposes a coming-of-age for a young girl whose childhood and early puberty are spent in hiding with several others in close quarters. Her wants, needs, likes, dislikes, what she understands, what confounds her, happinesses, disappointments, her faith, the complexities of the relationships with those whom she shares "captivity." How she feels about living in constant fear of being discovered.
The basic point of The Diary of Anne Frank is that it is the story of the Frank family and their friends who hid in an attic to try to escape deportation by the Nazis. While in the attic, Anne kept a diary. Only Anne's father survived the war, and when he returned to Holland, Miep Gies, who helped them hide, gave him the diary. This play is based on Anne's diary.
